I’ve been having a hard time figuring out how to create a link_to_remote
tag that would post a GET request with the value of a text_field as a
parameter, but without submitting the entire form.
The solution is both easy and elegant. Read the entire tutorial at

Hopefully this saves you a few hours of Googling and RTFM’ing.
